First lady shares 'fantasy' of just walking 'out the front door'

"We can't sneak out often on our own with security and motorcades and people with us," Obama said when asked about what she would change about her role as first lady. "But you know one fantasy I have — and the Secret Service keeps looking at me because they think I might actually do it — is to walk right out the front door and just keep walkin'.

"I can't up and decide 'I think I'm going to go for a walk, and I'm going to walk to Georgetown,' " she said. "So if I could change something, I'd be able to sneak around a little be more. But it caused people a lot of stress when I do that, so I try not to."

Sitting down for a half-hour with the children of White House and administrative staffers, Obama took questions on everything from her Let's Move! campaign, her career as a lawyer and what she likes to do on her birthday.

"One of the things we want you to know is that we know it's not easy having parents who are doing busy, important work," Obama said. "But because of the work they do, the country runs. And because you guys are handling your business — you're doing well in school, and you're staying out of trouble, and you're listening, and you're helping out at home when things are busy — you're helping your parents serve, too."
